Rihanna attended the Council of Fashion Designers of America Awards wearing a custom-made, see-through halter dress by Adam Selman.
The dress was embellished with 216,000 Swarovski crystals and paired with a matching sparkly turban.
Rihanna wore a flesh-colored thong but no bra under the sheer dress.
